Subject: Average of Array?

Message-ID: <AANLkTimbLPhLW7DzeTugvwClKBX-UQhOrUlR8afHydGB@mail.gmail.com> (raw)
Is there a function that returns the average of the elements of an
array? I'm thinking of something that would work like the avg()
aggregate function where it returns the average of all non-NULL
values. Can't find anything like it in the docs, and I'd like to make
sure I'm not missing something.
Thanks,
